abstract = {{The Wall Current Monitor (WCM) can monitor the lon-gitudinal beam shape, beam stability, beam longi-tudinal emittance and intensity, which has been ap-plied widely in the laboratories of high-current proton accelerators. Many accelerators such as CERN-PS, CERN-CLIC, J-PARC and CSNS-RCS have designed different WCMs according to their respective accelera-tor beam parameters. In order to provide the high-intensity heavy-ion accelerator facility (HIAF)-BRing high-frequency system of with the intensity of each harmonic beam to compensate for wake field; and to observe the changes of the bundle length during the injection, acceleration, and extraction of the bundle, it is planned to place a WCM in HIAF-BRing. According to physical requirements, the lower limit of the WCM work-ing bandwidth is expected to reach 10kHz, and the upper limit can reach 100MHz. According to this bandwidth re-quirement, a WCM structure is designed, and its theoretical bandwidth is 2kHz~400MHz, which fully meets the de-mand. This article gives a detailed and comprehensive in-troduction to the overall design of this WCM, the selection of various components, design calculations and related simulation calcula-tions. At present, the WCM has com-pleted the pro-curement and processing of various compo-nents, while offline and online testing has not been carried out owing to time constraints. It is expected to be in-stalled on the Heavy Ion Research Facility in Lanzhou-Cooling Storage Ring (HIRFL-CSR) for online testing in August.}},
